Snatched the motor out of the DKW this morning. It had a little water in it, but hopefully enough trans fluid to keep demon rust from forming. The brown milkshake was fairly clean, and easily washed off the clutch side of the engine.
Combustion chamber shows signs of abuse, and the piston is a bit tattered around the top ring land. Pin came out easily enough, and the small end needle bearing looked great.
And either the intake ports have been ported, or ze germans did some clean up work at the factory.
